            Bug ID: 30177
           Summary: Unexpected DOCTYPE declaration error
           Product: Validator
           Version: 1.1
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: check
          Assignee: dave.null@w3.org
          Reporter: nodropshots@gmail.com

  Target Milestone: ---

I am getting the following w3c error when checking my html document:
   Error Line 1, Column 1: end of document in prolog
<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML
…
✉
This error may appear when the validator receives an empty document. Please
make sure that the document you are uploading is not empty, and report any
discrepancy.

The xml instructions comes from an include (inc) file:

   <?php echo "<?xml version='1.0' encoding='UTF-8'?>"; ?>

as do the doctype declaration specifications:

   <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
   "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

The beginning of the html documents contains the following text:

   <?php error_reporting(E_ALL); ?>
   <?php include("includes/xml_instr.inc"); ?>
   <?php include("includes/map_doc_type.inc"); ?>

I have not changed the two include files for years, and have never seen this
w3c error message. In fact, the same error is encountered now on html web pages
generated several years ago, which never had the error.

Has something changed recently in the w3c validator to cause this error? If
not, what am I doing wrong?
